To the automotive industry circle, we do not feel strange about the term "light weight". The 

development of the automobile industry today, the consumer came up with more and more

 intense demand. In addition to the daily commute commuter use, power,handling, space, 

and fuel economy has become the common aspects which people need to consider.

But the few major parts of the automotive car can’t lack anyone. So if we want to improve the comprehensive

 performance effectively of the car, we only can make an issue of"lightweight" in the chosen material.

In fact, lightweight is to give the car slimming, to ensure stable performance on the basis of stability,

 to design the assembly components of energy-saving, to optimize models continuously. A large

 number of examples show that if the weight of the car reduces 1%, the fuel consumption can be

 reduced 0.7%; the whole weight of the car reduces 100 kg, 100 km’s fuel consumption can be

 reduced 0.3-0.6 L.

It is clear that the “light weight” can improve a lot to the automotive car. At present, lightweight technology is

 most widely used in aluminum alloy profiles.

△Early Versions of the Honda NSX Sports Car

The Honda NSX car which began to sell in 1990, was adopting the whole aluminum body.It was light 200kg 

than the same body made of cold-rolled steel plate. Because of the blessing of aluminum improves the NSX

performance, and won the reputation of "Japan Ferrari"

.

△ Jaguar XFL aluminum body structure

In recent years, Audi, Jaguar and Land Rover are using all-aluminum body structure, aluminum has become

 an ideal lightweight material. Aluminumalloy can be added the different proportions of the alloy as the diffe-

rent scaleand the different manufacturing process, to use in the body, frame, enginecylinder block, cylinder

 head, piston, intake manifold, rocker arm, enginemount bracket, actuator shell, clutch shell, brake parts and

 cover shell andother places. Effectively reduce the whole car’s weight, there by enhance the overall performance.

△ Tesla Model S Chassis structure

With the increasing of aluminum alloy body in recent years, the processingcosts reduce a lot; aluminum alloy

 profile is no longer the high technology forthe civil car.

Looking at the above factors, aluminum alloy profile is the most ideal large-scale production of lightweight

 materials. The importance of the aluminum alloy profile to the automotive industry’s current development

 is outstanding.
